Q: Regarding the AveoAir Ball Vents: They are pictured as a pair. Do they in fact come as a set of two?

No, that is for illustration purposes to show two different sizes. These vents are priced and sold individually.

Q: How much does each 2 inch Aveoair Ball Vent weigh?

Each of the Aveoair 2.00 inch ball vents weighs approximately 0.17 lbs. The 1.50 & 1.75 inch vents also weigh approximately 0.17 lbs.

Q: I see that other brands of vents boast STC approval. Is it necessary to have an STC to install these AveoAir Ball vents?

FAA approval is required to replace parts on certified aircraft. You should consult with your A&P mechanic to confirm this would apply to this vent, or if it would be considered a minor alteration.

Q: What is the maximum thickness of panel can these be used on?

Per Aveo: The front screws onto the SCAT back so theoretically one could use a thickness of up to almost the length of the shaft of the ball vent front, but not advisable as you would want to have the SCAT back securely turned on....

Q: Do these Aveoair ball vents twist to shut the air completely?

Yes, they do.
